TWO OLD NUNS

Sister Mary and Sister Louise rode a tandem bike to mass from the convent every day. Sister mary was always on the first seat.

One day Sister Louise decided she wanted to steer the bike and she decided to take a different route home.

When they reached the convent, Sister Louise fell off the bike and said "Oh Sister Mary, we've never come this way before."

Sister Mary replied with a chuckle, "I know, girl. It must have been the cobblestones."
